Seems to come from fixproto script:

+ test sys/types.h = NONE
+ test -f /xxx/gnu/gcc-3.0/objdir/gcc/include/sys/types.h -a -n ' include'
+ grep sys/types.h fixproto.list
+ true
+ rel_source_file=ansi_compat.h
+ abs_source_file=/usr/include/ansi_compat.h
+ abs_target_file=/xxx/gnu/gcc-3.0/objdir/gcc/include/ansi_compat.h
+ test ansi_compat.h = NONE
+ test -f /xxx/gnu/gcc-3.0/objdir/gcc/include/ansi_compat.h -a -n ' include'
+ grep ansi_compat.h fixproto.list
+ true
+ rel_source_file=strings.h
+ abs_source_file=/usr/include/strings.h
+ abs_target_file=/xxx/gnu/gcc-3.0/objdir/gcc/include/strings.h
+ test strings.h = NONE
+ test -f /xxx/gnu/gcc-3.0/objdir/gcc/include/strings.h -a -n ' include'
+ grep strings.h fixproto.list
+ true
+ rel_source_file=sys/../h/types.h
+ abs_source_file=/usr/include/sys/../h/types.h
+ abs_target_file=/xxx/gnu/gcc-3.0/objdir/gcc/include/sys/../h/types.h
+ test sys/../h/types.h = NONE
